Print Quality Command

Although you can turn on the draft mode with one of the panel
buttons, you can also use a software command to switch between
draft and Letter Quality.
Enter and run the following program to see how Letter Quality and
draft are turned on and off by an ESCape sequence (note that you use
a lowercase x, not a capital X, in line
NEW
10 LPRINT CHR$(27)"x0";
20 LPRINT "This is draft."
LPRINT CHR$(27)"x1";
30
40 LPRINT "This is Letter Quality."
As you can see in this program, Letter Quality is one of the Epson
modes with an ESCape code that uses a letter with the numeral one to
the mode and a letter with the numeral zero to turn it off. For
turn on
these modes, the one or zero can be inside the quotation marks, as
shown above, or as a separate character string value, as shown below:
10 LPRINT CHR$(27)"x"CHR$(0);

Other Widths

The three basic widths (pica, elite, and fifteen) cannot be combined
with each other. If one is on, the other two are off. There are, how-
ever, two width modes that can be combined with the basic modes
and with each other. These two are double-width and condensed. All
characters printed by the LQ are widened by double-width and nar-
rowed by condensed.

Double-width printing

The double-width mode doubles the width of each character. To see
double-width pica printing, which is the widest typestyle available on
the LQ, enter and run the program below.
